The flares are not a difficult install. There is no drilling. They are installed with clips. Some people have reported that there were issues with the fit but my flares installed with no issue.
Glad you are enjoying your new ride. I installed the fender flares and splash guards in the front. It involves trimming the splash guards but it can be done.
Occasionally my screen blacks out when I use the USB port and go the Waze app when I am on the highway. If I unplug the cord and reinsert the screen comes back on.
